ERCOT

The Electric Reliability Council of Texas formed in 1970, is one of eight Independent System Operators in North America, and is the successor to the Texas Interconnected System (TIS). TIS originally formed in 1941 when several power companies banded together to provide their excess generation capacity to serve industrial loads on the Gulf Coast supporting the US war effort for World War II. ERCOT is one of nine regional electric reliability councils under North American Electric Reliability Corporation (NERC) authority. NERC and the regional reliability councils were formed following the Northeast Blackout of 1965. ERCOT’s offices are located in Austin and Taylor, Texas.
